APPARATUS FOE DISPLAYING ANNOUNCEMENTS, ADVERTISEMENTS, AND THE LINE.-

To all whom it may concern Be it known that we, AUGUSTUS BERNARD POWELL, subjects of the King of Great Britain, residing/at Gerrards Cross, Buckingham, and London, England, respectively,

. have invented new and useful Improvements in Apparatus for Displaying Announceinents, Advertisements, and the like, of which the following is a specification.

This invention relates to improvements in apparatus in which announcements, pictures,

and the like are exhibited on a screen; and the objects of our improvements are, first, to provide a device in which announcements, advertisements, drawings, and the like are produced at the apparatus itselfand can be immediately thrown upon the screen as produced; secondly, to arrange that by the use of the well known tele-writer mechanism an announcement, or drawing may be transmitted automatically to a number of displaying points at the same time. v

The apparatus by means of which this invention is carried out embraces the use of a telautograph machine (such for instance as that patented in America under No. 656,828

and known commercially as the Telewriter) arranged with its writing point or tracing arms adapted to operate in the path ofa shaft of light projected from a lantern containing a strong source of light, which is condensed by a suitable optical system, and projected on to a screen.

The invention consists in passing a strip of paper, of transparent or translucent nature, directly across the optical systemof a projecting lantern, provision being made in the latter for the support of a transparent plate, or surface, between the lenses of the said system, and the actuating mechanism of the tracing arms of the telewriter, being disposed in a position adjoining the transparent plate, but so as'not to appear in front of same except as regards the tracing arms, which'write directly on the paper strip.

In the drawing accompanying this specification, Figure 1 is a view partly in section of a lantern and its optical system, with the telautograph mechanism applied thereto,

the latter, not being claimed as new, being shown in dotted lines. The telautograph apparatus shown in the Specification of Letters Patent.

ner, and writes on the paper strip b, which is drawn off the rollw and on to the roll a intermittently. lhe condenser s of theoptical system also occupies a space between the motors, while the lantern 1" containing thesource of light 1* is placed behind them.

a is a magnetic paper shifter of any known form which causes the strip 6 to travel off the roll to on to the roll ,2,- in unison with the paper shifter at the transmitting station, both rolls being spring checked. The particular paper shifter we use in practice is illustrated and described with reference to Figs. 10,11, 12, 13, of

American Patent No. 656,828.

h is a suitable framing for carrying various parts, and a screen z opposite the apparatus receives the image projected by the optical system. The paper guide a is carried upon partitions or brackets connected to the framing, while the tracing arm at is connected: to levers k flexibly attached to the motor armatures in theordinary way;

The mode of operation'and action of the telewriter is well-known; ,suflice it to state therefore that in use the tracing pen Z on the tracing arm (Z inscribes'upon the paper a reproduction of the original writing or design inscribed by-the operator on the transmitter, and as the inscription on the paper. band?) takesplace in the illuminated area of the condenser s an image of such inscription is projected ,by the objective lens t on to the screen'z'. Thus, the inscription appears to the observer as though beinganade upon the screen itself. I 1

The telewriter receiving mechanism is preferably arranged to trace the writing or drawing in an inverted position so that the an erecting'prism or lens system for arriving at the same result. Several receiving plates may be operated from one telewriter transmitting station.

Instead of the translucent screen i the image may be thrown direct upon an opaque screen placed in 'front of the apparatus. It may be thrown in any other direction desired such as on to the screen i by means of a reflector such as m placed in front of the object lens.

" Whatwe claim as our invention and desire to secure by Letters Patent is:

, 1 The combination, in apparatus for displaying announcements, advertisements, drawings, and the like. of an optical light- "pi' ofjectin'g system, a strip of translucent ma- '.terial, means for gulding and intermittently traversing the said strip between condensing and object ve lenses of the said optical system, means for directly wrltlng, prlnting,

or drawing on the portion of said strip within the field of the light rays, and a screen receiv'ing' the projection of the said writing,

" printing, or' drawing.

The combination, in apparatus for disolavin 'jannouncements drawin s, and the e b V 3 b like, of an optical ligh'tprojecting system,

' the receiving plate and tracing arm of a tele-writer or telautograph machine arranged between the condensing and objective lenses of the said system, a strip of translucent materlal guided across the sald "quired, tele-writer transmitting means of known form for causing the tracing arm to receiving plate, a magnetic paper shifter of known form operated by the tele-writer to shift the strip forward intermittently as rewrite, print, or draw, on the strip on the said-receiving plate, and a screen receiving the projection ofthe said writing, printing, or drawing, all substantially as set forth.

3; In apparatus fordisplaying announce ments, drawings, and the like, the combination of a lantern containing a strong source of light, condensing lenses attached thereto, objective lenses on the same principal axis as thecondensing lenses, a tele-writer receiving mechanism and magnetic paper shifter, a frameworl'r having an adjustable support for the objective lenses and carrying the lantern the said tele-writer mechanism and the paper SlllftQIiSO that the tele-writer mechanism is located between the condensing and objective lenses of the optical system, astrip of translucent material passin over the telewriter receiving plate, and rollers supported by the said framework, one releasing and one automatically receiving the translucentstrip carried thereby, substantially as described.

L 'In apparatus for displaying announcements. drawings, and the like, the combination ofa--l:mte1'n containing a str i'g source of light, condensing lenses attached thereto, objective lenses on the same principal axis as the condensing lenses, a tele-writ'er receiving mechanism and magnetic paper shifter, a

framework having an adjustable support sired direction, and a receiving screen coacting with the said reflector to receive the said image.

In testimony whereof we have signed our names to this speclficatlon 1n the presence of two subscribing witnesses.
